I booted knoppix on my dell inspiron 8100. Everything seems to work great until I let it sit for 5 or 10 min. Then the screen blanks out. When I wiggle my mouse to get the screen to come back, my screen is split funny. The top of my desktop comes in about the middle of my screen. Then when I move my mouse to the bottom of the screen (middle of the desktop), it will pass through the bottom of the screen and come out the top until it hits the bottom of the desktop, which is about in the middle of my screen again. I don't have a screen saver set and I disabled my power management, so I'm confused what it's blanking the screen out after a certain amount of time and why it's messing up the screen on resume!

Any ideas?
